Braking Systems

Today we talk about how many types of braking system are there . Mainly there are four Types of braking system used in vehicles and they are :

1. Mechanical Brakes
2. Hydraulic Brakes
3. Booster Brakes
4. Air Brakes

Mechanical Brakes : Mechanical Brakes use lever , rods and wires to work , as in when u press the lever it pushes the wire which causes the braking pad to stick to the drum creating friction to stop the car , it is a simple braking system which consists of levers and wires , it is mostly used in bicycles and low powered motorbikes now a days

this is just a bicycle brake 

Hydraulics Brakes : Hydraulic brakes consists of cylinders , pipelines and proportional valves . This type of  braking system uses fluid , which when becomes pressurized creates extra force then what is applied to it . when u press the pedal the fluid inside the master cylinder is compressed so it travels to the moveable point creating extra force but when reached it is blocked by the pad which starts to push the pad or shoes towards the disc or drums and applying brakes this type of system is used in almost all the passenger cars

A simple working of hydraulic brake system

Booster Brakes : Although its is similar to the hydraulic braking system , this is system consists of another part which is called a booster which increases the applied force by using the engine vacuum created in the intake manifold . It consists of a diaphragm which is static until the pedal is pushed which cause the diaphragm to move in the direction of the master cylinder pushing the piston with it and creating a multiple force on the piston to push the brake fluid to the brake cylinders this pushing the pad against the disc with increased force

This is a vacuum booster

There is an air power booster as well which instead of vacuum uses compressed air to work and multiply the force , but cars mostly use the vacuum type since it as lesser parts then the air powered one thus cheaper to manufacture and powerful enough to stop the car

Air Brakes : This is a totally different type of  braking system which consist of

1. Compressor
2. Air Compression tank
3. Relief Valves
4. Air Lines 
5. Pedal Valve 
6. Air Wheel cylinders
7. Air Release valve 

With all these thing in one braking system its hard to image where it would all fit especially a tank of compressed air and its compressor, well this type of braking system does not come in passenger cars or sports cars , It is a system designed for medium and heavy duty truck and trailers . Because even though trucks and trailers don't have high speeds the load it carries causes a hurl effect on the truck causing it to lose traction thus powerful brakes are required by them to stop properly with heavy load

That is a lot for a car to handle

there are air brakes in cars as well but not like this one , they are different and work at high speeds and they only consists of a motor and a hydraulic spoiler 

And Finally if people are confused that where is the ABS Braking system , well for your information ABS is not a braking system itself it is a assist system put on booster or hydraulic braking system to provide good traction in any weather and its main purpose is to stop brake locks which happens when u push the pedal too hard causing the tyres to lock on and lose traction causing accidents

Well that's it ! Hope This Was helpful

Thanks to all !
